What is a sinus infection ?

Sinus infections , also called sinusitis , defined as an inflammation of one or more sinuses. Sinuses – hollow cavities within the facial bones . The sinuses are lined by mucous which normally produce a liquid – normally the liquid flows into the nasal passages and is ingested during the day. However, when the land for the drainage of the sinuses are blocked sinuses can not drain , and the infection may develop.

The actual sinus infection frequently caused by a viral infection (such as the common cold ) but may also be bacterial in nature (and thus responds to antibiotics). Little sinus infections is due to fungus and mold in the sinuses.
Sinus infections can be divided into different categories , the first based on how long the infection continued :

Acute sinusitis: Infection represent less than four weeks , and include ” classic” symptoms of facial pain or pressure on the involved sinus, colored nasal discharge (green, yellow , milky or gray), nasal congestion , headache, fever , back – nasal drip and cough .

Subacute sinusitis: Infection are more than four but less than eight weeks. Symptoms may be less severe and only include nasal congestion or posterior- nasal drip .

Chronic sinusitis: a gift infections within eight weeks or more , and similar to that of subacute sinusitis symptoms can be mild and consist of nasal congestion , back – nasal drip , mild headaches , chronic cough and fatigue. Some people may be mistaken as having allergies when, in fact , they have a chronic sinus infection .

Recurrent sinusitis: Defined as three or more sinus infections annually . They may be due to not fully treat chronic sinus infections or new infections with various bacteria.

What are the symptoms of sinusitis ?

The following symptoms tend more contact with acute sinusitis ( subacute and chronic forms of sinusitis may be less severe symptoms , especially pain )

Facial pain and pressure on the involved
Nasal congestion
Colored nasal discharge
Decrease in the smell and taste sensations
Bad breath / bad taste
Tooth pain
Ear pressure / pain
Post nasal drip

Do Sinus Infection Causes Allergies ?

There is increasing evidence to support the idea that allergies may predispose a person to developing sinus infections . As inflammation in the nasal passages , whether caused by an irritant or allergic infection (such as the common cold ) , sinus drainage blocking sites lead to a sinus infection . Therefore , allergic rhinitis ( hay fever) may lead to sinus infections indirectly.

What else can cause Recurrent sinus infection ?

Other causes of recurrent sinus infections include structural abnormalities within the nasal passages and sinuses, such as a deviated septum (the structure that divides the nasal passage on two sides ) , and other bony disorder that can prevent sinus drained . These disorders are usually found on computed tomography (CT or “cat” view) of the sinuses , and is typically treated with surgery, such as septoplasty .

Problems with low free function , called immunodeficiency may predispose individuals to different types of infection , including sinusitis. Typically, the availability problems associated with the formation of an antibody to cause pneumonia and sinusitis .

Immunodeficiencies may occur as a result of genetic problems (such as cystic fibrosis ) , as a result of infection (such as HIV / AIDS) , as well as other diseases that affect the levels of antibodies (such as multiple myeloma ) . Allergists / immunologists are uniquely qualified to assess and treat people with impaired immune systems .

Other diseases may increase the chance for a person sick sinus infections , including gastroesophageal reflux disease (GERD) and non-allergic rhinitis . Treatment of these causes can improve or reduce episodes of sinusitis.
